Pavlovian bias and modelled parameters.

Left) Pavlovian performance bias calculated from the behavioural data contrasting reward based invigoration and punishment based-suppression. A larger value indicates greater Pavlovian bias. Right) Parameters extracted from the final reinforcement learning model used to fit the data. Means and 95% HDI of the posterior are presented obtained from a robust Bayesian t-test.

左侧为基于行为数据计算得到的巴甫洛夫（Pavlovian）绩效偏差，该指标对比了奖赏驱动的行为激活与惩罚驱动的行为抑制。数值越大，代表巴甫洛夫偏差越强。右侧为从用于拟合该数据集的最终强化学习（reinforcement learning）模型中提取的参数，本次展示的后验分布均值与95%最高密度区间（Highest Density Interval, HDI）均通过稳健贝叶斯t检验得到。
